libata#upstream now defaults to hardreset. softreset is used only as
followup-SRST in case hardreset can't classify or PMP is supported, so
there's no reason to add reset promotion logic anymore.

After modularize patchsets, sata_link_hardreset() does all the chores
needed around hardreset and sata_mv should be able to just build a loop
around it.
Thanks.
